On the United Parcel Service website(UPS) there is a form where you can enter a zip code and it will return a color coded map that shows shipping times from that zip code. I am trying to use URLExecute[] to automate a search. At this stage I'm just trying to get it to return a particular map. Looking at the HTML code, I can see that the input field for the zip code is labeled "zip" and so I tried:

URLExecute["https:/www.ups.com/maps", {"zip" -> "90210"}]

which returns

"HTTP Status 404 - Not Found
Type Status Report
Description The origin server did not find a current representation
